Endogeneity and exogeneity of first-mover opportunities First-mover advantages are typically the result of two things: technical proficiency (endogenic) and luck (exogenic). Technical proficiency and manufacturing capability can significantly influence a company's ability to sustain a first-mover advantage. A technologically superior product may capture market share more quickly, while a novel product entering an untested market has the potential for substantial growth. Firms with strong technical competencies are often able to produce goods at lower costs than competitors, supporting both pricing strategies and marketing efforts. Procter & Gamble's introduction of the first mass-market disposable diaper serves as a frequently cited example; the company leveraged technical innovation, cost-efficient materials, established manufacturing processes, and existing distribution channels to gain a dominant position in the disposable diaper industry. Luck can also have a large effect on profits in first-mover-advantage situations, specifically in terms of timing and creativity. Simple examples such as a research "mistake" turning into an incredibly successful product (
serendipity), or a factory warehouse being burned to the ground (unlucky), can have an enormous impact in some instances. Initially, Procter and Gamble's lead was aided by its ability to maintain a proprietary learning curve in manufacturing, and by being the first to take over shelf space in stores. Large increases in the birth rate, in the years that Procter and Gamble's first disposable diapers were released, also added to their industry profits and first-mover advantage.
Definitional and measurement issues What constitutes a first-mover? Much of the problem with the concept of first-mover advantage is that it may be hard to define. Should a first mover advantage apply to firms entering an existing market with technological discontinuity, the calculator replacing the slide rule for example, or should it apply solely be new products? The imprecision of the definition has certainly named undeserving firms as pioneers in certain industries, which has led to some debate over the real concept of first-mover advantage. Another common argument is whether first-mover advantage constitutes the initiation of research and development versus the entry of a new product into the market. Typically the definition is the latter, since plenty of firms spend millions in research and development that never result in a product entering a market. Many factors affect the answer to these questions; including the sequence of entry; elapsed time since the pioneer's first release; and categorizations such as early follower, late follower, differentiated follower, etc.
Alternative measures of first-mover advantage A commonly accepted way of measuring a first-mover advantage is by measuring the pioneering firm's profits as the consequence of its early entry. Such profits is an appropriate measure, since the sole objective of stockholders is to maximize the value of their investment. Still, some issues have risen with this definition, specifically that dis-aggregate profit data are seldom obtainable. In turn, market shares and rates of company survival are typically used as alternative measures since both are commonly linked to profits. Still these links can be weak and lead to ambiguity. Early entrants always have a natural advantage in market share, which does not always translate to higher profits.
Magnitude and duration of first-mover advantages Though the name "first-mover advantage" hints that pioneering firms will remain more profitable than their competitors, this is not always the case. Certainly a pioneering firm will reap the benefits of early profits, but sometimes profits fall close to zero as a patent expires. This commonly leads to the sale of the patent, or exit from the market, which shows that the first-mover is not guaranteed longevity. This commonly accepted fact has led to the concept known as "second-mover advantage". ==Second-mover advantage==
